[Application of MRI in the diagnosis of glomus tumor]
Objective:
To discuss the necessity of MRI as a routine examination for diagnosis of glomus tumor.
Methods:
From Nov. 2013 to July 2014, 7 cases of glomus tumor were treated in our department. All patients had typical clinical symptoms of glomus tumor and received preoperative X-ray and/or MRI examination. The diagnosis was confirmed by postoperative histopathologic examination. All the patients were retrospectively analyzed by reviewing the preoperative examination results and PubMed search results.
Results:
2 cases underwent only X-ray examination before operation with no positive results. 3 cases underwent both X-ray and MRI. No positive finding happened in X-ray, while MRI showed glomus tumor characteristic on T1- and T2-weighted images which demonstreated a more intense signal after injection of gadolinium. The last 2 cases underwent only MRI examination, which revealed positive images of glomus tumor.
Conclusions:
MRI plays an important role in diagnosis of glomus tumor and should be adopted as a routine examination.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
